Why does the Pivot Table Default to Count?

One of the most common questions I see on my free 3-part video series on pivot tables & dashboards is, “Why does the pivot table default to Count instead of Sum when I add a field to the values area?”

We can t summarize this field with Sum because its not a supported calculation for text data types

Well, Pivot Tables have some rules on which calculation type will be selected when we add a field to the Values area.

The rules are pretty simple:

  • If ANY cell in the column (field) contains text, blanks, or errors (#N/A, #REF!, #VALUE!, #NAME?), then the calculation type will default to COUNT.
  • If ALL cells in the column (field) contain numbers, then the calculation type will default to SUM.

Now that we know the rules, we can prevent this error by cleaning up our data.

How to Prevent the Default Count Calculation Type

Let's take a look at 3 ways to make sure the calculation type defaults to Sum.

1. Replace Blank Cells with Zeros

In the video above I show a data set that contains blanks in the Revenue column.  Since there are blanks in this column, the pivot table calculation type defaults to Count.

One quick way to fix this is to replace the blank cells with a zero (0) value.  Here are instructions on how to find & replace all blanks in a column.

  1. Select all cells in the column or Table (keyboard shortcut: Ctrl+Space Bar).
  2. Open the Replace Window from the Home tab on the Ribbon in the Find & Select menu (keyboard shortcut: Ctrl+H).
  3. Delete everything in the Find What text box so it finds blank cells.
  4. Type a zero 0 in the Replace With box.
  5. Press the Replace All button (keyboard shortcut: Alt+A).
  6. Refresh the pivot table (keyboard shortcut: Alt+F5).
  7. Add the field to the Values area of the pivot table.

The calculation type should default to a Sum calculation if all cells in the data source column are numbers.

2. Replace Errors with Zeros

Blank cells are the most common cause that I see for calculation type defaulting to Count.  However, cells that contain text or errors can also cause this problem.

If the source data column contains a formula that is returning errors, we can use an IFERROR function to return a zero instead of the error.  Of course we will want to determine why the error is occurring in the first place.

My free 3-part video series on the lookup formulas has an entire video dedicated to learning how to prevent and fix errors with formulas like VLOOKUP and INDEX/MATCH.

3. Convert Text to Numbers

Sometimes values in cells look like numbers, but the numbers are stored as text.  This is a common issue when you are importing data into Excel from another system.  In this case we will need to convert the text to numbers first.  Checkout my article on keyboard shortcuts to convert text to numbers to learn more about these techniques.

PivotPal's Auto Sum/Count Feature

At the end of the video I also explain how PivotPal can save time with this issue.  PivotPal has it's own rules for adding a field to the values area, and does NOT default to count if the column contains blanks.

If the column contains numbers and blanks, PivotPal will default the calculation type to Sum when we add the field to the values area using the PivotPal window.  This is one way to get around this annoying issue without having to modify the source data.

What Other Issues Cause the Calculation to Default to Count?

Is your calculation type still defaulting to Count?  This is typically due to one or more cells that are NOT numbers.  Please leave a comment below with any other issues that I might have missed, or any questions you have.  Thank you! 🙂

Why is my sum not working in pivot table?

Reason No. Excel expects your numeric data to be 100% numeric. If you have a dataset with 50,000 rows of numbers and one blank cell in the middle, the pivot table will count instead of sum. There is an easy way to convert the blanks to zero.

Can you use sum in calculated field?

Sum is the only function available for a calculated field. A calculated field becomes a new field in the pivot table, and its calculation can use the sum of other fields. Calculated fields appear with the other value fields in the pivot table.

How do you summarize text cells in Excel?

Select the column to summarize on With a cell selected in an Add-In for Excel table, click the ACL Add-In tab and select Summarize > Summarize. Select a column of any data type to summarize on.

How do I enable a calculated field?

On the Analyze tab, in the Calculations group, click Fields, Items, & Sets, and then click Calculated Field. In the Name box, type a name for the field. In the Formula box, enter the formula for the field. To use the data from another field in the formula, click the field in the Fields box, and then click Insert Field.
